A series of bizarre assaults is mystifying Boston police:
an unknown attacker is viciously beating random strangers
and leaving a note quoting an old warning about
witchcraft. History professor Alex Maple was one of the
victims, and now he's gone missing. Vickie Preston is
certain that someone has taken her friend for malicious
purposes. She's having blood-drenched visions that seem to
be staining her waking life, and the escalating attacks
suggest that a dangerous cult is at work behind the
scenes-a cult so powerful that its members would rather
die than be apprehended.

Vickie is grateful to have Special Agent Griffin Pryce and
the FBI's elite Krewe of Hunters on her side. Vickie and
Griffin are finding their way in an increasingly
passionate relationship, and he's keeping her safe and
sane amid the disturbing investigation. The search for
Alex will take them deep into the wilderness of
Massachusetts on the trail of a serial killer, where an
ancient evil is waking.
